There is a reason why you would want to put on the whole armor of God. We are fighting a spiritual enemy and it’s not our wives, our neighbors, or our bosses. Our enemy is Satan. So we need God’s armor to protect us against him and his attacks.
Far too many times, we think we can take on Satan but we’d be foolish to do so. Greater is He who is in us than he who is in the world (1 John 4:4). It is only by standing behind Jesus and submitting to God that we can overcome the Devil (James 4:7). If we know who the enemy is, we would know how we can overcome him. When we know how big our God is, we will see how small our enemy is.
